Patent number: 8421319Abstract: A bearing holder mounting structure which allows a motor to be manufactured with a small number of parts without needing complex processing, and such motor are provided. A rotor 1 having a pair of bearings 5A and 5B and a washer 28 mounted thereon is inserted into an opening portion 23a of a motor housing 7 such that a rotor member 11 of the rotor 1 is received in a receiving concave portion 23. A bearing holder 9 is disposed on a bottom wall portion 29a of a fitting recessed portion 29 such that a flange portion 37 of the bearing holder 9 abuts on the bottom wall portion 29a of the fitting recessed portion 29. A retaining fitting 33 is then pressed into the fitting recessed portion 29 such that six engaging pieces 41 are located at positions slightly deviated from positions of six lead-out groove portions 31.Type: GrantFiled: August 3, 2009Date of Patent: April 16, 2013Assignee: Sanyo Denki Co., Ltd.Inventors: Yukio Miura, Mitsuaki Shioiri

Patent number: 7939980Abstract: A motor, in which a creep phenomenon can be prevented and a ball bearing can readily be mounted, is provided. A pair of end brackets each have a bearing hole in which a ball bearing is fitted. A pair of ball bearings are fitted into the bearing holes of the end brackets such that an outer race portion of each ball bearing may abut on a first wall surface and a second wall surface of the end bracket. A stopper fitting is pushed into a recessed portion of the end bracket until a ring portion of the stopper fitting abuts on the outer race portion of the ball bearing. Six engaging pieces of the stopper fitting are engaged in a fourth wall surface defining the recessed portion due to a restoring force of the engaging pieces, which have been resiliently bent or warped, to restore from the bent or warped state. Thus, each ball bearing is tightly fixed in the bearing hole by means of the stopper fitting.Type: GrantFiled: July 31, 2009Date of Patent: May 10, 2011Assignee: Sanyo Denki Co., Ltd.Inventors: Yukio Miura, Mitsuaki Shioiri
